Body with a Surface Structure Which Enhances the Friction Behavior

Abstract

Described is a body, comprising an elastomeric material or having an outer elastomeric layer, wherein a surface structure which enhances the friction behavior is formed into the surface of the elastomeric body or into the outer elastomeric layer of the body. The surface structure ( 1 ) has a pattern made up of protuberances ( 11 ) which are prismatically, frusto-pyramidally, cylindrically, frusto-conically or mushroom-shaped, are spaced apart by passages ( 12 ) and the surfaces of which define a common plane, the maximum surface area of the protuberance ( 11 ) being in the range of from 100 nm to 5 mm.
